Question

A jar contains 6 red balls , 5 green balls, 3 white balls and 7 yellow balls . two balls are chosen from the jar with replacement . what is the probability that both balls chosen are white ? Also what is the probability of choosing a red then a green ball​

Answer 1

Answer:

it's the answer

Step-by-step explanation:

Number of green balls = 3

Total number of balls = 6 + 3 + 5 +7 = 21

Probability of picking a green ball once = 3/21=1/7

Probability of an event happening twice when theevents are independant is simply their probability squared so:

Probability of picking 2 green balls = (1/7)^2 = 1/49
